Oh, this should be fun.

I wonder if they'll lock/cripple the PC version to a lower frame-rate and resolution as well.

Assassin's Creed Unity will run at 900p/30fps on both PlayStation 4 and Xbox One, Ubisoft has confirmed, with the publisher opting to aim for platform parity to avoid discussion over the differences in performance.
"We decided to lock them at the same specs to avoid all the debates and stuff," senior producer Vincent Pontbriand told VideoGamer.com while explaining that it's the consoles' CPUs – not the GPU – that prevents Ubisoft Montreal from improving the game's performance.
